Get easy Shields and protect DE (if structures are max Up'd)

Attachment 80978

What do you think? Good design? Bad design?

I am TH7. All my buildings and walls are Max upgraded so I have no need for gold.
That's why my gold storage is outside and next to my TH.
Now I get painless Shields without losing DE or Elixir.
Since using this design I have only lose DE one time from a triple Lightning spell.
90% of the time players steal my gold storage, kill my TH and leave.

Also, do you like the design of my wall openings?
I have 3 wall openings, or funnels.
Each opening is offset at a 90 degree angle, and then 1 tile away from the opening I place a 90 degree diagonal door stopper, using a few wall pieces.

Now I can put the Spring traps on either side of that door stopper (it funnels the units down narrow hallways) or inside the opening. I can also put the springs away from the openings where the walls are narrow.

I also intentionally have several 2x2 tile empty spaces where tesla or giant bombs can be. This is to discourage hogrider raids.

Please give me feedback. thanks
